Question

the perimeter of a rectangle is 52 cm. The length of the rectangle can be represented by (x.+5) and its width can be represented by (3x-7) what are the dimensions of this rectangle?

Answer 1

Length=11

Width=11

Explanation:

P (perimeter) is 52 so

2(x+5)+2(3x-7)=52

then

2x+10+6x-14=52

8x-4=52

8x=48

x=6

so
