Question

find the area of triangle with base 4.9cm and hypotenous 5cm

Answer 1

Base = 4.9cm
Hypotenous = 5 cm
height = ✓(5)² - (4.9)²
= ✓25 - 24
= 1cm
Area of triangle will be = 1/2*base*height
=1/2*4.9*1
= 4.9/2
= 2.45 cm²
Therefore area of triangle is 2.45 cm²

Hope this helps you...:)

Answer 2

hello frnd!!

here's ur answer....

given:-

base=4.9cm

hypotenuse=5cm

we know that a²+b²=c²

therefore=

4.9²+b²=5²

24.01×b²=25

b²=25-24.01

b²=0.99cm

b=√0.99cm

area of the triangle=1/2×b×h

=1/2×√0.99×4.9

=2.43cm²

hope this helps...
