Question

3. Find the area of the agricultural field
ABCDEF whose measurements in metres
are given in Fig. 14.18 in which ABDE is a
rectangle and ZC = 90°.

Answer 1

Answer:

57,500

Step-by-step explanation:

Area of field = area of rectangule ABDE + area of ∆AFE + area of ∆BCD

.'. Area of rectangule = l×b = 150×250 = 37,500

.'. Area of ∆AFE = 1/2 × base × height

= 1/2 × 40 ×250= 5,000

.'. Area of ∆BCD= 1/2 × base × height

= 1/2 × 150 × 200

= 15,000

.'.Total area = 37,500+5,000+15,000

= 57,500
