triangle as shown in adjoining figure.
Sides of big triangle are 25cm, 26cm and 28cm. Also,
∆ is formed by joining mid points of sides of ∆ .
Answer the following.
a) What is the semi – perimeter of ∆?
b) ½ of AB = ____
i) QR ii) RP iii) QP iv) QC
c) What is the length of RQ?
d) If colouful rope is to be placed along the sides of ∆. What is the length of
the rope?
e) Area pf ∆ =
i) − 12.5 − 13 ( − 14) ii) − 25 − 26 ( − 28)
iii) + 12.5 + 13 ( + 14) iv) + 25 + 26 ( + 28)
Where s is semi – perimeter of ∆.

Answer 1

Answer:

A modulus function is a function which gives the absolute value of a number or variable. ... The plotting of such graphs is also an easy method where the domain will be all values of input say x (all real numbers) and range will be all values of function (y = f(x) = all positive real numbers and 0).
