Question

Find the area of the shape given below

Answer 1

Answer:

1/2*b*h

1/2*2*4

4cm^2-outer figure  (triangle)

s=2cm

s^2

2^2=4cm^2

0cm^2

Answer 2

Let the sum be 'x'.

Given that Sum of money amounts to (7/4) of itself.

Sum = (7/4) * x

= (7x/4).

Time = 3 years.

∴ SI = (7x/4) - x

= (7x - 4x)/4

= 3x/4

∴ Rate = [(SI * 100)/P * T]

= [3x * 100]/x * 3 * 4]

= 25

Therefore, rate of interest = 25%.
