Answer:
b = 6 mm
Step-by-step explanation:
Using Pythagoras' identity on the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
b² + 8² = 10²
b² + 64 = 100 ( subtract 64 from both sides )
b² = 36 ( take the square root of both sides )
b = = 6
Answer:
Step-by-step explanation:
The figure consists of 2 rectangles.
<u>Rectangle 1 Area:</u>
Length = 5 cm
Width = 2 cm
Area = Length * Width
A = 5 * 2
A = 10 cm²
<u>Rectangle 2 Area:</u>
Length = 4 cm
Width = 2 cm
Area = 2 * 4
A = 8 cm²
<u>Area of the whole figure:</u>
= Rectangle 1 + Rectangle 2
= 10 + 8
= 18 cm²
