Question

Find the perimeter of the rectangles of the following measures.

A. Length $=12cm$ and Breadth $=21cm$ __________

B. Length $=20cm$ and Breadth $=19cm$ _____________

C. Length $=7cm$ and Breadth $=9cm$ __________

D. Length $=44mm$ and Breadth $=60cm$ _____________

Answer 1

Perimeter of rectangle $=2(l+b)$

$A\left)2\right(12+21)=66c{m}^2$

$B\left)2\right(20+19)=78c{m}^2$

$C\left)2\right(7+9)=32c{m}^2$

$D\left)2\right(44+60)=208c{m}^2$

Hence, this is the answer.
