Question

Find the height of tha trapezium if the length of the two parallel sides are 12cm and 14cm and the areas of the trapezium is 143cm^2

Answer 1

Answer:

Step-by-step explanation:

area of the trapezium=143cm2

let the sides be a=12cm and b=14cm

area of trapezium = 1/2(H)(a+b)

                     143=1/2(h)(12+14)

                      143=1/2(h)(26)

                       143*2/26=h

                             h=11cm
