Question

hep me to find the sum​

Answer 1

Answer:

x=8.25m or 8 5/20m

Step-by-step explanation:

LET OTHER PARALLEL SIDE= x

Area=21×Sum of parallel sides×Distance between them.( so area is given instead of writing A we should write the sum)

480m²=21×15+x×20m

480m²=315+20x metre

20x m=480m²-315 ( it is because if Positive sign value comes on other side it becomes negative sign)

20x m=165m² ( so now for finding x, 20 m will go other side so 20m and x are in multiplication, if multiple value goes other side it will be in divided form)

x=165m²/20m

x=8.25m or 8 5/20m
