Question

the length of a rectangle is represented by 2x + 4 and width is 3x + 6 the perimeter is 55 units find the value of x

Answer 1

Explanation:

P = 2(l+b)

55 = 2(2x+4 + 3x + 6)

55 = 2( 5x + 10)

55= 10x +20

10x = 55 - 20

X = 35/10

X = 7

Answer 2

x = 3.5

Explanation:

P= 55

l= 2x+4

W= 3x+6

P= 2(L+W)

55= 2(2x+4+3x+6)

55=2(5x+10)

55=10x+20

35=10x

3.5=x
