Answer:
118.3 m²
Step-by-step explanation:
Step 1. Calculate the <em>semiperimeter</em> (s).
s = (p + q + r)/2
s = (17 + 18+ 15)/2
s = 50/2
s = 25 m
===============
Step 2. Calculate the <em>area</em> (A).
Use <em>Heron’s formula</em>:
A = 118.3 m²
Answer:
42.8%
Step-by-step explanation:
Step one:
given data
A department store buys 100 shirts at a cost of $700
let us find the cost of 1 shirt
cost of 1 shirt= 700/100= $7 per shirt
The cost price per shirt = $7
We are given that the selling price = $10 per shirt
Step two:
The percent markup can be found as
percent markup= selling-cost price/cost price*100
percent markup= 10-7/10*100
percent markup= 3/7*100
percent markup= 0.428*100
percent markup= 42.8%
