Question

find the area of a rectangle length =18 and breath =10​

Answer 1

Answer:

area of rectangle = length × breadth

area = 18 × 10

area = 180

Answer 2

• Given

• Length of rectangle = 18 cm
• Breadth of rectangle = 10 cm

• To find

• Area of rectangle

• Solution

Area of rectangle = length × breadth

Substitute the given values,

⇒ (18 × 10) cm²

⇒ 180 cm²

• Area of rectangle = 180 cm²
