Question

find find the perimeter and area of the right and right triangle with base 4 cm and height 3 cm​

Answer 1

Answer:

Perimeter = 12 cm

Area = 6 cm²

Explanation:

Base = 4 cm

Height = 3 cm

Hypotenuse = √(Base)² + (Height)²

= √4² + 3²

= √16 + 9

√25 = 5 cm

Perimeter = a + b + c

= 4 + 3 + 5

= 12 cm

Area = 1/2 × b × h

= 1/2 × 4 × 3

= 2 × 3

= 6 cm²

Answer 2

Answer: 12 cm , 6 cm²

Explanation:

So first we will find the hypotenuse

i.e. h²=b²+p²

h²=(4 x 4 ) + (3 x 3)

h²= 16 + 9

h²= 25

h= 5

Perimeter = 5+4+3

= 12cm

Area = 1/2 x b x h

= 1/2 x 4 x 3

= 6 cm²
