Question

the area of a triangle and it's height with respect to some base are 1256 sq .mm and 31.4 . mm respectively , then then length of the base is​

Answer 1

Answer:

Base=b=8mmb=8mm

Step-by-step explanation:

Given,

Area of triangle=A=1256mm^{2}A=1256mm

2

Height of triangle=h=314mm=h=314mm

Base of triangle=b =?=b=? mmmm

Solution,

Area of triangle A=1/2\times b\times hA=1/2×b×h

1256=1/2\times b\times 3141256=1/2×b×314

b=1256\times 2/314b=1256×2/314

b=8mmb=8mm

Base of triangle is 8mm8mm

Answer 2

The area of triangle = 1256sq mm

The height of triangle =31.4mm

we know that,

The area of triangle =1/2×base×height

so, 1256=1/2×3.14×base

so, here base =1256×2×10/3.14

so, base =80 mm
