I= PRT

7280=26000×0.07T

7280\1820=1820T\1820

4=T

A linear equation is an equation in which the highest power of the variable is always

Diagonal of the parallelogram divides the parallelogram in to two equal areas.

So area of parallelogram = 2(area of triangle)

According to the given diagram,

AB= 8, AD = 5 and BD = 11

So according to the Heron's formula,

Area of triangle =

and a, b and c are the three sides of the triangle

Area of triangle ABD =

So, area of parallelogram ABCD = 2(area of triangle ABD)

area of parallelogram ABCD = 2 (18.33)

area of parallelogram ABCD = 36.66

area of parallelogram ABCD = 36.7 sq. units
