Question

draw a rectangle whose two adjacent sides are 6.5 cm and 4.5 cm draw a triangle equal in area to this rectangle ( construct by figure)​

Answer 1

Area of Triangle = Area of Rectangle= 58.5

1. 1st - Find area of Rectangle = Length x Breadth

• length= 6.5 cm

• breadth= 4.5 cm

• Area of Rectangle = 6.5 cm x 4.5 cm

                              = 29.25 cm².

1. 2nd - Area of Triangle = 1/2 x base x height

• when u read the question say the area of rectangle and area of triangle both are equal so let's do it.
• Area of Triangle = Area of Rectangle
•    1/2 x base x height = 29.25 cm²
•     base x height = 29.25 cm² x 2

•     base x height = 58.5 cm².

now suppose base and height are the same numbers is = y

• Base = Y

• Height = Y

• Y x Y = 58.5 cm²
• Y² = 58.5 cm²
• Y = √58.5 cm²
• Y = 7.6 (Approx)

1. Base = 7.6 (Approx)
2. Height = 7.6 (Approx)

• The Triangle base and height is depending on the area of a rectangle who to break it and divide it into base and height. base value increase and height value decrease and also vice verse.
