the parallel sides of a trapezium are 20 cm and 10 cm. Its non parallel are both equal each being 13cm. Find the area of the trapezium.​

Step-by-step explanation:

a = 20 cm

b = 10 cm

c = 13 cm

Distance between the parallel sides is found using the Pythagoras theorem.

Area of a trapezium is given by

The area of the trapezium is

a. 12.5 kg

step-by-step explanation:

f = ma

so

m = f/a = (2500 n)/(200 m/s²) = 12.5 kg

1 n = 1 kg·m/s²
