Question

two angles 9f a triangle are eqal and the third anglebs measures 70 degree find the measure of each of the unknown angles​

Answer 1

Answer:

Answer

Let the length ,breadth and height is l , b and h respectively

Then area of four wall of room =2h(l+b) sq m

If length breath and height is twice. Then length=2l breadth ,=2b and height =2h

Then area of new room wall=2×2h(2l+2b)=8h(l+b) sq m

But cost of plastering the four walls Rs 25

Then cost of plastering the four walls of new room=

2h(l+b)

8h(l+b)×25

=100 Rs
