Answer:
The answer for (The length of a rectangle is 16 cm and the length of its diagonal is 20 cm. The area of the rectangle is)
C) 192cm
Step-by-step explanation:
First we have to find breadth using pythagoreas theorem
A^2 + B^2 = C^2
Let a be 16
16×16 + B^2 = 20×20
256 + B^2 = 400
B^2 = 400-256
B^2 = 144
B = ROOT OF 144
B = 12
NOW WE CAN FIND AREA USING THE FORMULA (LENGTH × BREADTH)
16×12
= 192cm
Hence area is 192cm
