Question

What is the area's of triangle,circle,rectangle,trapezium,square?

Answer 1

Area of :

1) triangle = 1/2×b×h

2) circle = πr^2

3) rectangle = l×b

4) trapezium = 1/2 (a+b)h

5) square = s×s

Hope it helps you.....

Answer 2

the perimeter formula for all these are :-

triangle = sum of all sides

circle = 2πr

rectangle = 2(l+b)

trapezium = sum of all sides

square = sum of all sides

the area formula are;:-

triangle= 1/2×hieght × base

circle =πr2

rectangle = length × breadth

trapezium = a+b/2

square= side× side
