Question

A table-top measures 2 m 25 cm by 1 m 50 cm. What is the perimeter of the table-top?

Answer 1

Length of table top = $2$ $m$ $25$ $cm$
= $2.25$ $m$
Breadth of table top = $1$ $m$ $50$ $cm$
= $1.50$ $m$
Perimeter of table top = $2$ $\times$ $(length + breadth)$
= $2 \times (2.25 + 1.50)$
= $2 \times 3.75 = 7.50$ $m$

Thus, the perimeter of table top is $7.5$ $m$.
