The area of a rectangle is equal to its length times its width. If the area of a rectangle is 4x +20 which options could be the length and width of that rectangle

The required option are

Length = 4 and width = x+5

Length = 2 and width = 2x+10

Step-by-step explanation:

Area of the rectangle = Length × width

Given

Area = 4x+20

Factoring out the common terms

Area = 4x + 4(5)

Area = 4(x+5)

Length = 4 and width = x+5

This can also be written as

Area = 2(2x+10)

Length = 2 and width =2x+10

i think it is 18

step-by-step explanation:

so, converting firstly the mixed fractions to improper fractions and then "adding".
