Question

find the area of trapezium height is 15cm parallel asides are 10cm. and 12cm

​

Answer 1

Step-by-step explanation:

Area of trapezium=21× sum of parallel sides×  distance between them

=21×(10+12)×4=44cm2

Answer 2

AnSwER -:

165 cm^2 is the area of trapezium

_____________________________

Explanation-:

The formula to find area of trapezium-:

“A = 1/2 x h x(a+b)”

A= Area

H= height

A+ b = sum of parallel sides

————————————————————

Given ,

H = height = 15 cm

A+b = sum of parallel sides = 10cm+12cm

To find ,

Formula to find area -:

1/2 x h x (a+b)

= 1/2 x 15 (10 cm+ 12 cm )

= 1/2 x 330

= 165 cm^2

165 cm^2 is the area of trapezium.

Formulas to find area of different shapes

Parallelogram-: 1/2 x d1 x d2 , d = length

of diagonal

Trapezium-: 1/2 x h x (a+b) , h= height

a+ b = sum of the parallel sides
