Question

the length of one side of a rectangle is p cm and width is 3(p-2) cm the perimeter is 44 cm find the length and width of rectangle​

Answer 1

Length = 7cm, Width = 15cm

Explanation:

Length = p

Width = 3(p-2)

= 3p-6

Perimeter = length + width + length + width

= p + 3p-6 + p + 3p-6

= 8p-12

8p - 12 = 44

Isolate 8p.

8p = 44+12

= 56

Find p.

p = 56 ÷ 8

p = 7

Length = 7cm

Width = 3(7)-6

= 21-6

= 15cm
