Question

The area of trapezium of height 12m is 138sqm, if one of the parallel sides is 15m what is the length of the other side​

Answer 1

Length of the side is 8 m

Step-by-step explanation:

1. Let the other side be x m
2. area of trapezium = sum of parallel sides × height/2
3. 138 m² = (15m + x) × 12m/2
4. 138 m²= (15m + x) × 6m
5. 138m²/6m= (15m + x)
6. 23m= 15m + x
7. 23m-15m = x
8. 8m = x
