Question

A verandah is 40 m long and 15 m broad. It is to be paced with stones, each measuring 6 dm by 5 dm. find the no. of stones required.

Answer 1

Convert Meter into Decimeter= 40×10dm =400dm and 15×10dm= 150dm
Area of Verandah= 400dm × 150dm = 60000dm^2
Area of stone= 5dm × 6dm = 30 dm^2
Number of stones required= 60000/30= 2000 stones.
Hope it helps

Answer 2

Veradah =L×b
=40x10 dm×15×10dm
= 400dm×150dm
=60000dm
Given, 6dm×5dm
=30dm
Hence. No of stone required =60000/30
2000stone ans
