Question

The area of a triangle having 10 cm base and 16 cm height is -----cm^2 *​

Answer 1

Answer:

48 cm square

Step-by-step explanation:

Given

Base=16cm

Lengh of both equal side =10cm

We will use Herons's formula to find the area

a=16cm

b=10cm

c=10cm

Therefore,

Halfperimeter =s=21×(16+10+10)

=236

s=18cm

using Heron's formula

s(s−a)(s−b)(s−c)

=18(18−16)(18−10)(18−10)=18×2×8×8=2×9×4×2×4×2×2=3×2×2×2×2=48cm2

hence,

The area of given triangle is 48cm2

Answer 2

Answer:

We know,

Area of a triangle= 1/2 × Base × Height sq. unit

= 1/2 × 10 × 16 cm²

= 5 × 16 cm²

= 80 cm²

Answer: 80 cm²
