Question

PLS HELP ( CORRECT GETS BRAILY )

The design of the home is shown below. If all measurements are in millimeters, find the area of the diagram.

Answer 1

In the above fig, Let the base of Traingle be x

cos 60° = Base/Hypotenuse = 1/2

x / 30 = 1/2

x = 15 mm

sin 60° = Perpendicular/Hypotenuse = √3/2

Perpendicular = 30√3/2 = 15√3

___________________

Now find the Length of other Parallel side. let say it y.

x + y = 51

15 + y = 51

y = 36 mm

Finding the side of Square in figure

Side of Square = 36/3 = 12 mm

____________________

Now lets Find the AREA of Individual figure

AREA of Trapezium

• 1/2 × Sum of || side × Height
• 1/2 × (36 + 51) × 15√3
• 1128.825 mm²

AREA of Square

• Side²
• 12²
• 144 mm²

AREA of House

• 1128.825 - 144
• 984.825 mm²
