Question

The rectangle has a length of -2x + 10 and a width of 10. a) Find the area of the rectangle and simplify.​

Answer 1

Answer:

• Area = -20x + 100
• Perimeter = -4x + 40

Step-by-step explanation:

Given rectangle with

• Length l = - 2x + 10
• Width w = 10

To find

• Area
• Perimeter

Solution

• A = lw
• A = (-2x + 10)*10 = -20x + 100
• P = 2(l +w)
• P = 2( -2x + 10 + 10) = 2( -2x + 20) = -4x + 40
