Question

here are some easy maths question... solve it... thank u​

Answer 1

Step-by-step explanation:

i)Area of rectangle=l×b

Area of rectangle=40×20

Area of rectangle=800cm*

Area of triangle=1/2×l×h

Area of triangle=1/2×20×10

Area of triangle=100cm*

Area of two triangles=200cm*

Area of shaded region =800cm*-200cm*

Area of shaded region=600cm*

ii)Area of one triangle=100cm*

Area of two triangles=200cm*

iii)Rectangle

iv)perimeter of rectangle =2(l+b)

perimeter of rectangle=2(20+40)

perimeter of rectangle=2×60

perimeter of rectangle=120cm
