250 Questions: Perimeter, Area and Surface Area

Front

What is the formula for the area of a rhombus?

Back

Area = (d1 * d2) / 2, where d1 and d2 are the lengths of the diagonals.

Front

How do you calculate the area of a circle?

Back

Area = π * r², where r is the radius.

Front

What is the formula for the total surface area of a rectangular prism?

Back

Total Surface Area = 2(lw + lh + wh), where l is length, w is width, and h is height.

Front

If the length of a rectangle is 20 m and the breadth is 15 m, what is its area?

Back

Area = length * breadth = 20 m * 15 m = 300 m².

Front

What is the area of a semicircle with diameter 14 m?

Back

Area = (π * r²) / 2, where r = diameter / 2 = 7 m. Area = (3.14 * 7²) / 2 = 76.93 m².

Front

What is the value of π (pi) approximately?

Back

π ≈ 3.14.

Front

How do you find the perimeter of a rectangle?

Back

Perimeter = 2(length + breadth).

Front

What is the formula for the area of a triangle?

Back

Area = (base * height) / 2.

Front

How do you calculate the surface area of a cube?

Back

Surface Area = 6 * (side length)².

Front

What is the relationship between the radius and diameter of a circle?

Back

Diameter = 2 * radius.
