Question

Find the perimeter of a rectangle whose length is 30 m and a diagonal measure 34 m​

Answer 1

Answer:

480 cm²

Step-by-step explanation:

• Length of a rectangle = 30 cm

• Measure of one of its diagonals = 34 cm

So,

• We can get the breadth by PYTHAGORAS THEOREM.

(Breadth)² = (Diagonal)² - (Length)²

(Breadth)² = (34)² - (30)²

(Breadth)² = 1156 - 900

(Breadth)² = 256

Breadth = √256

Breadth = 16 cm

So,

• Perimeter of the rectangle = 2(Length + Breadth).

= [ 2(30 + 16) ] cm

= [2× 46] cm

= 92 cm

• Area of the rectangle = Length × Breadth

= (30×16) cm²

= 480 cm²

Answer 2

Answer:

length=30 m

diagonal=34 m

breadth=16 m

Perimeter =92 m
