Question

the area of trapezium is 360cm2 the length of parallel side is 20cmand height is 20cm fint the other parallel sde

Answer 1

Answer:

Other Parallel Side = 16cm

Step-by-step explanation:

here, one of its parallel side = 20cm  and height = 20cm

Area of Trapezium = $\frac{1}{2}$ × (sum of parallel sides) × height

                 360cm² = $\frac{1}{2}$ × (20 + $x$) × 20

            360cm²/10 = 20 + $x$

      36cm² - 20cm = $x$

                            $x$ = 16cm

∴ the other side = 16cm

hope it will help you.

Answer 2

Step-by-step explanation:

Area of trapezium= a+b/2×h

Given Area= 360cm²

a=20cm

h=20cm

Area=a+b/2×h

360=20+b/2×20

360=(20+b)×10

360=200+10b

360-200= 10b

160= 10b

b=16cm

other parallel side=16cm
