please solve this...
tomorrow is my exam

Answer 1

2)
Area of floor = l×b=5×4=20msq

So number of tiles required is 20/ 1/2= 40sqm
----------------------------------------------------------------------

3)Area of triangular land = 1/2 ×base× height

A= 1/2 ×30×40 =600sqm

Area of rectangular land = l×b
A= 20×15= 300

Triangular land > Rectangular land

∆ land is best to purchase.
–--------------------------------------------------------------------

4) Area of Mani s land (square) =side^2

A= 50^2= 2500sqm

Area of Ravi s land (Rectangle) =l×b
A= 60×40 =2400sqm

so Mani is benefited by 100sqm land.
--------------------------––----------------------------------------

5). Area of Right Triangle = 1/2 ×base × height

A=1/2×60×80= 2400sqcm

Area of square = side^2 = 50×50=2500sqcm

so Square has large area .
