Question

Find the perimeter of a rectangle whose length is (4a+b)cm and width (a+6)cm​

Answer 1

Given below

Hope it helps

Explanation:

Perimeter= 2(l+b)

= 2(4a+b+a+6)

= 2(5a+b+6)

= 10a+2b+12 cm^2

Answer 2

P = 10a +2b+12

Explanation:

P = 2 (l+w) for a rectangle

P = 2 ( 4a+b + a+6)

Combine like terms

P = 2(5a+b+6)

Distribute

P = 10a +2b+12
