Question

Write the following information in mathematical form. the length of a rectangle is twice its breadth and its perimeter is 52.

Answer 1

Given Length $=2\times$ breadth
perimeter of rectangle $=2\times (l+b)$
Therefore $52=2(l+b)$
$52=2(2b+b)$
$52=2\left(3b\right)$
$\frac{52}{2}=3b$
$26=3b$
$\frac{26}{3}=b$
breadth of rectangle is $\frac{26}{3}$
length of rectangle is $2\times \frac{26}{3}=\frac{52}{3}$.
