Question

The parallel sides of a trapezium are 12 cm and 17 cm. If non-parallel sides equal, each being 6.5 cm, find the area of the trapezium​

Answer 1

Step-by-step explanation:

Area of trapezium=1/2*h*(a+b)

Area of trapezium=1/2*h*(a+b)a=12cm

Area of trapezium=1/2*h*(a+b)a=12cmb=17cm

Area of trapezium=1/2*h*(a+b)a=12cmb=17cmh=6.5cm

Area of trapezium=1/2*h*(a+b)a=12cmb=17cmh=6.5cmarea=1/2*6.5*(12+17)

Area of trapezium=1/2*h*(a+b)a=12cmb=17cmh=6.5cmarea=1/2*6.5*(12+17)=1/2*6.5*(29)

Area of trapezium=1/2*h*(a+b)a=12cmb=17cmh=6.5cmarea=1/2*6.5*(12+17)=1/2*6.5*(29)=94.25sq.cm

Answer 2

Step-by-step explanation:

Area of Trapezium :

a = 12cm

b = 17 cm

h = 6.5 cm

$\implies$ $\sf{A={\Large\frac{1}{2}}×h(a+b) }$

$\implies$ $\sf{{\Large\frac{1}{2}}×6.5(12+17) }$

$\implies$ $\sf{{\Large\frac{6.5×29}{2}} }$

$\implies$ $\boxed{\sf{A=94.25cm^2 }}$
