Question

Find the sum of length of base of a trapezium whose area is 42 cm² and whose height is 6 cm​

Answer 1

Answer:

area = b + h

42 = b + 6

42÷6 = b

7 = base

pls mark me brainliest.

Answer 2

Step-by-step explanation:

area of trapezium= 1/2{sum of bases}×height

so area= 1/2{sum of bases}×6

42=1/2{sum of bases}×6

sum of bases= (42×2)/6

sum of bases= 14 cm
