Question

A square technology chip has an area of 25 square centimetres. How long is each side of the chip ?

hintHint:

Use the formula of area of square.

The correct answer is: a = 5 cm


    Complete step by step solution:
    Area of the square chip = 25 cm2…(i)
    Let the length of each side of chip = a
    We know that the formula for area of square = a2…(ii)
    On equating both, we get a2 = 25

    Now take square roots on both the sides, we have a = square root of 25
    rightwards double arrow a space equals space 5
    Hence length of each side of chip = a = 5 cm
