Question

The length of a rectangle is 8 cm more than its width if the perimeter of the rectangle is 44 cm.Find the dimension of the rectangle if its perimeter is 80 cm

Answer 1

Answer:

Step-by-step explanation:

Perimeter=2(Length+width);

Given that length is 8cm more than width;

L=W+8;

Perimeter=44=2(W+8+W);

22=(2w+8);

22-8=14=2w;

W=7cm; Width of rectangle is 7cm and length is 8+7=15cm.

Now if perimeter is 80cm;

Then

80=2(w+w+8);

40=2w+8;

32=2w;

Width=16cm;

Length=W+8=16+8=24cm
