Question

please solve it Question fast Plz ​

Answer 1

Area of trapezium

= 1/2 × h ( sum of parallel sides)

height = 280 cm = 2.8 m

so

4.2 = 1/ 2 × 2.8 × ( a + b )

4.2 × 2 = 2.8 × ( a + b )

8.4 / 2.8 = ( a + b )

3 = ( a +b)

sum of parallel sides = ( a +b ) = 3

hope it helps

Answer 2

Given,

Area of trapezium = 4.2 m^2

height = 280cm= 2.8m

sum of heights = 2 ×4.2÷2.8 =3m

Hope this helps❤️❤️
