Question

if sum of 9000 becomes 10440 and certain rate of simple interest for two years in how many years will the sum of 12000 amount to 15840 at the same rate of interest​

Answer 1

Answer:

The two parallel sides be a & b

Distance between parallel sides be h

Given,

a = 22

b = 16

h = 11

Formula for area of trapezium

A = [( a+b )× h] ÷2

Putting the values of a,b,h in equation

A =[(22+16)×11]÷2

A =[38×11]÷2

A = [418]÷ 2

A = 209 square unit.
