Rectangles: 3540

The dimensions of the left rectangle are 4 cm and (x+1) cm. The right rectangle consists of two rectangles: the upper one with dimensions of 3 cm and x cm and the lower one with an area of 7 cm2. We know that the area of the left rectangle is the same as the area of the right rectangle. Determine x.

Correct answer:

x =  3

Step-by-step explanation:

S1=S2 S1 = 4 (x+1) S2= 3 x+7  4(x+1)=3x+7  4 (x+1)=3 x+7  x=3  x=13=3  x=3
