Question 392658
Trapezium (american -trapezoid - if two sides are parallel).
The area of a trapezium/trapezoid is given by:
{{{A = ((b[1]+b[2])/2)*h}}}
The two bases are:
{{{b[1] = 20}}}m.
{{{b[2] = 15}}}m.
The height is:
{{{h = 12}}}m.
Make the appropriate substitutions:
{{{A = ((20+15)/2)*12}}} Evaluate.
{{{A = 210}}}sqare metres.
The cost of the fertilizer at Rs.5 per square meter for 210 square meters is:
{{{5*210}}} = Rs. 1050
