Answer:

x = 8.17

Step-by-step explanation:

We will be using pythagoras theorem:

a^{2} + b^{2} = c^{2}

=> 4.25^{2} + x^{2} = 9.21^{2}

=> x^{2} = 84.8241 - 18.0625 = 66.7616

=> x = \sqrt{66.7616} = 8.17077719.. = 8.17 (3 s.f)

Use the formula to determine the area of squares with side lengths of 3 cm, 10.5 cm, and π cm.
Nataliya [291]

Answer:

For length of side = 3 cm

Area of the square = 9 cm²

For length of side = 10.5 cm

Area of the square =  110.25 cm²

For length of side = π cm

Area of the square = 9.869 cm²

Step-by-step explanation:

The area of a square is given as :

Area = Side²

therefore,

For length of side = 3 cm

Area of the square = ( 3 cm )² = ( 3 × 3 ) cm² = 9 cm²

For length of side = 10.5 cm

Area of the square = ( 10.5 cm )² = ( 10.5 × 10.5 ) cm² = 110.25 cm²

For length of side = π cm

Area of the square = ( π cm )²  

= ( π × π ) cm²                

= 3.14² cm²                                [π = 3.14]

= 9.869 cm²
