Answer 1

Question ::-

Length of parallel sides are 10 cm and 15 cm , and height of trapezium is 8 cm find the area of trapezium ?

Given ::-

• Length of parallel sides = 10 cm and 15 cm

• Height of trapezium = 8cm

To find ::-

• Area of trapezium ?

Solution ::-

Area of trapezium ::-

= $\dfrac{1}{2}$ × ( sum of ll sides) × height

= $\dfrac{1}{2}$ × ( 10+ 15) × 8

= $\dfrac{1}{\cancel{2}}$ × 25 ×$\cancel{8}$

= 25 × 4

= 100 cm .

Area of trapezium = 100 ${cm}^{2}$

Answer 2

Step-by-step explanation:

$area \: of \: trapezium \: \: = \: (a + b) \frac{1}{2} \times h$

= (10+15)×1/2×8

= 25 × 4

= 100cm²
