You are going to use an incline plane to lift a heavy object to the top of a shelving unit with a height of 8 ft. The base of the incline plane is 11 ft from the shelving unit. What is the length of the incline​ plane?

Step-by-step explanation:

This is a right triangle. The floor and the shelf would form a 90 degree angle. The Pythagorean theorem states that the sum of the squares of the legs is equal to the square of the hypotenuse.

8^2+11^2=x^2

185=x^2

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2
