let me know if this is right
Expert:  M Hasan replied 4 years ago.

We first find the length of CA:

CA = √(61^2 + 68.6^2)
CA = 91.8

Angle BCA:

tan BCA = 68.6/61
BCA = 48.36º

ACD = 105 - 48.36º = 56.64º

We will find the length of road frontage (AD) using the cosine rule.

AD = √(CD^2 + CA^2 - 2(CD)(CA) cos ACD)
AD = √(109.5^2 + 91.8^2 - 2(109.5)(91.8) cos 56.64º)

Therefore, the road frontage is 96.76 m.

Area = (1/2)(61)(68.6) + (1/2)(109.5)(91.8) sin 56.64º
Area = 6290.22

Therefore, area is 6290.22 m^2.

Hope this helps. If so, please click 'Accept'. Thanks! :)

can you show formula for the area
Expert:  M Hasan replied 4 years ago.
Yes, sure.

Area = Area of right triangle ABC + Area of triangle ADC
Area = (1/2)(BC)(BA) + (1/2)(CD)(CA) sin ACD
Area = (1/2)(61)(68.6) + (1/2)(109.5)(91.8) sin 56.64º
Area = 6290.22

Hope this helps. If so, please click 'Accept'. Thanks! :)
