Question

Helppppppppp find the area of a rectangle that has a length of x+3 and a width of 2x-7

Answer 1

6x + 20

Explanation:

A = 2(l) + 2(w)

= 2(x+3) + 2(2x+7)

= 2x + 6 + 4x + 14

= 6x + 20

Answer 2

2x² - x - 21

Explanation:

Given :-

• l = x + 3
• w = 2x - 7

Finding Area :-

• Area = l * w
• A = ( x +3)(2x - 7)
• A = x (2x - 7 ) +3( 2x -7)
• A = 2x² - 7x + 6x - 21
• A = 2x² - x - 21
