Question

the length of the boundary of the trapezium ABCD is 70cm . if AD is perpendicular to the parallel side AB and CD, find the area of Trapizium​

Answer 1

Answer:

Area of the trapezium is 270 $cm^{2}$.

Step-by-step explanation:

Length of Side AD = Perimeter - (Sum of the rest 3 sides)

                               = 70 - (20 + 25 + 13)

                               = 70 - (58)

                               = 12 cm

Area of Trapezium = 0.5 * Height * (Sum of both Parallel Sides)

                               = 0.5 * (AD) * (20 + 25)

                               = 0.5 * (12) * (45)

                               = 6 * 45

                               = 270 $cm^{2}$

Answer 2

Area of the trapezium is 270 cm^{2}cm

.

Step-by-step explanation:

Length of Side AD = Perimeter - (Sum of the rest 3 sides)

= 70 - (20 + 25 + 13)

= 70 - (58)

= 12 cm

Area of Trapezium = 0.5 * Height * (Sum of both Parallel Sides)

= 0.5 * (AD) * (20 + 25)

= 0.5 * (12) * (45)

= 6 * 45

= 270 cm^{2}cm
