Question

4 In Fig. 14.30, calculate:
a) the length of AB
b) area of trapezium ABCD
c) area of ABCD
​

Answer 1

Answer:

(a) 24 cm

(b)180 cm^2

(c)

Step-by-step explanation:

(a) By pythagoras property,

A^2 + B^2 = C^2

10^2 + AB^2 = 26^2

100 + AB^2 = 676

AB^2 = 676 - 100

AB^2 = 576

AB = 24 cm

(b) Area of trapezium = a + b x h

2

12 + 24/2 x 10

36/2 x 10

180 cm^2

(c) 180 cm^2

Hope this answer helps you....
