Question

6. The area of a triangle and its height with respect to some base are 1256
sq.mm. and 31 4. mm respectively, then length of the base is -​

Answer 1

Base=$b=8mm$

Step-by-step explanation:

Given,

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

Height of triangle$=h=314mm$

Base of triangle$=b =?$$mm$

Solution,

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

$1256=1/2\times b\times 314$

$b=1256\times 2/314$

$b=8mm$

Base of triangle is $8mm$
