Question

he length and width of a rectangle are 7 cm and (x - 8) cm respectively. Find the value of x if the area of the rectangle is 42 cm2.

Answer 1

Answer:

⇒x = 14

Step-by-step explanation:

Given:

Length(l) = 7 cm

Width(b) = (x-8) cm

Area of the rectangle = l*b

42 = 7(x-8)

⇒x-8 = 42/7

⇒x-8 = 6

⇒x = 6+8

⇒x = 14
