Question

how can u measure area of regular shape by using graph paper?


please explain by writing/ drawing​

Answer 1

Answer:

Area of a regular shape can be measured by using a graph paper by counting the number of boxes lie under the shape.

Explanation:

Procedure:

• At first put the shape on the graph paper.
• draw the outline of the shape on graph paper.
• Counting the boxes inside the drawn outline.
• If the area of one box is 'A' unit and there are 'n' boxes inside the outline.
• Then area of the shape will be = A × n unit.

Example:

• Suppose a square box is placed on a graph paper to measure area of the base of the box.
• By drawing the outline, we get 40 boxes. So, n = 40.
• Now the area of one small box of the graph paper= A = 1 mm²
• Then area of the base of the box = 1 × 40 = 40 mm²
