Mrs. Alexander wants to make a rectangular quilt that will have an area of 80 square feet So far, she has made 16
squares for the quilt each 2 feet long and 2 feet wide. Does she have enough squares to complete the quilt?

No, she doesn't have enough square to complete the quilt. Mrs. Alexander need 4 more squares to complete the rectangular quilt, that will have an area of 80 square feet.  20 square required to make quilt.

Step-by-step explanation:

The given is,

                Area of an rectangular quilt - 80 square feet

               She made 16 squares

               Square have 2 feet long and 2 feet wide

Step:1

             Area of rectangular quilt = 80 square feet

             Area of 16 squares = 16 × Area of square..................(1)

            Formula for area of square,

                                       ................................(2)

           Where, a - Sides of square

                        a = Length = Wide

           From given,

                        a = 2 feet

          Equation (2) becomes,

                                          A = 4 square feet

         Equation (1) becomes,

                          Area of 16 squares = 16 × 4

                                                          = 64 square meters

         Area of rectangular quilt ≠ Area of 16 squares

                                    80 ≠ 64

         Area of square is less compare to area rectangular quilt, so we need more square,

       Required amount of square area = 80 - 64

                                                               = 16 square feet

               Required amount of squares =

                                                                = 4 squares

       Total(16+4) square areas = 20 × 4 = 80 square feet

          Area of rectangular quilt = Area of 20 squares

                         80 square feet = 80 square feet

Result:

         No, she doesn't have enough square to complete the quilt. Mrs. Alexander need 4 more squares to complete the rectangular quilt, that will have an area of 80 square feet. 20 square required to make quilt.

they can both be solutions depends on the equation

step-by-step explanation:

what is the equation? ?

r and t.

both are 64 degrees.
