Question

the area of a trapezium field is 480 meters square the distance between two parallel sides is 15 m and the length of 1 parallel sides is 20 m find the length of the other parallel side
in this answer I will give more marks with full explanation and previous sum also
​

Answer 1

Answer:

44 m

Step-by-step explanation:

Given: area= 480 m2

d1 = 15 m

d2 = 20 m

let  d3 = x

ATQ

area = 1/2 *d1 * (d2+d3)

480 = 1/2 * 15 * (20+x)

2(480) = 15*(20+x)

2*480/15 = 20+x

64 = 20+x

x = 64-20

x = 44 m

Answer 2

Step-by-step explanation:

Given

Area of trapezium = 480m²

Distance between between parallel sides i.e.

Hight = 15 m

one of parallel side = 20 m

To find

Length of other parallel side =?

SOLUTION

let the length of parallel sides " x m "

we know that

area of trapezium = 1/2× sum of parallel

480= 1/2×(x+20) × 15

480× 2 = 15 (x+20)

960= 15 ( x+20)

960/15=x+20

x=64-20

x= 44

Elegant of other parallel side 44}}
