Question

A trapezium named pqrs with right angles at q&r. PQ equals to 9 cm, PR equals to 4 cm and RS equals to 6 cm. calculate the perimeter of a trapezium

Answer 1

Explanation:

Draw a picture. Seriously, this time you need to, so you can see that PS is the hypotenuse of a right triangle with legs of length 3 and 4 .

PS = √(3² + 4²) = 5

Perimeter = PQ + QR + RS + PS = 9 + 4 + 6 + 5 = 24 cm
