Question

Elsie is planning a rectangular section of grass if the perimeter of the rectangle is 96 ft what is the length and width of the rectangular section the width is 6x - 15 and the length is x​

Answer 1

• 39 ft and 9 ft

Explanation:

Given:

• P = 96 ft
• w = 6x - 15
• l = x

Use perimeter equation and solve for x:

• P = 2(l + w)
• 2( 6x - 15 + x) = 96
• 7x - 15 = 48
• 7x = 63
• x = 9

Find the width:

• w = 6*9 - 15 = 39
