Learning task 2 solve the following problems. Write your answers in your notebook
1. The perimeter of a quadrilateral is 412.95 cm. If the three known sides
measure 85.56 cm, 112.77 cm, and 85.26 cm, how long is the fourth
side?
2. I bought 4 items worth Php 39.90, Php 68.60, Php 58.75 and Php
120.25. How much change will I get from Php 500-bill?
3. A rectangle is 13.8cm. long and 9.7 cm wide. Find its perimeter.
4. Obed and Dario hiked 15.1 km. In one day and 13.75 km in the next
day. How many kilometers did they hiked
Answers
Step-by-step explanation:
1. perimeter of quadrilateral = sum of all side
give, perimeter=412.95 cm, m.of 1st side=85.5 cm, m. of 2nd side=112.77cm, m. of 3rd side=85.26 cm
let the fourth side be x
so, 412.95cm = (85.5+112.77+85.26+x) cm
412.95 cm = 283.53cm + x
x= (412.95-283.53)cm
x=129.42cm
2. sum of all four items = (39.90+68.60+58.75+120.25)php
total price= 287.5 php
change I will get from php 500 bill= (500-287.5)php
= 212.5php
3. perimeter of rectangle= 2(l+b)
given, length=13.8cm and width=9.7cm
so, 2*(13.8+9.7)cm
= 2*23.5cm
= 47 cm
therefore, perimeter of rectangle is 47 cm
4. distance hiked in one day = 15.1km
distance hiked next day = 13.75km
distance hiked in total
= (15.1+13.75)km
= 28.85 km
so, they hiked 28.85 km in both days.
