Question

find the area of a field a b c d e f whose measurements in metre are given in figure 13.40 here acdf is a rectangle and angle E is equal to 90 degree​

Answer 1

Answer:

57,500

Step-by-step explanation:

Area of ABCDEF = Area (ABC) + Area (ACDF) + Area (DEF)

= (1/2×40×250)+(250×150)+(1/2×200×DE)

= 5000 + 37500 + (100×DE)

= 42500 + (100×DE)

For DE, in triangle DEF, using Pythagoras theorem:

250^2 = 200^2 + DE^2

62500 = 40000 + DE^2

DE^2 = 22500

So, DE = 150

Therefore, Area (ABCDEF) = 42500 + (100×150)

= 57,500
