### Math in Focus Grade 6 Chapter 10 Quick Check Answer Key

**Solve.**

Question 1.

The length of a rectangle is 15 meters and its width is 8 meters. Find the area of the rectangle.

Answer:

Given that the length of a rectangle is 15 meters and its width is 8 meters.

Formula to find the area of rectangle will be,

= length × width

Here length = 15m and width = 8m

= 15×8

= 120 sq.m

**Solve.**

Question 2.

A side length of a square is 10 centimeters. Find the area of the square.

Answer:

Given that a side length of a square is 10 cm.

Formula to find the area of a square

= length×length

= 10×10

= 100sq.cm

Thus, the area of square will be 100sq.cm

**Name each figure and identify the pairs of parallel lines.**

Question 3.

Answer:

Given figure RSTU is similar to rhombus.

In rhombus opposite sides are parallel to each other.

Here, line segment RU is parallel to ST and RS is parallel to UT.

Therefore, RS and UT, RU and ST forms the pairs of parallel lines.

Question 4.

Answer:

Given figure EFGH is similar to parallelogram.

In parallelogram opposite sides are parallel to each other.

Here, line segment EH is parallel to FG and EF is parallel to HG.

Therefore, EH and FG, EF and HG forms the pairs of parallel lines.

Question 5.

Answer:

Given figure has two opposite sides of different lengths which is similar to the properties of trapezium.

Therefore, we can assume the given figure to be a trapezium.

In trapezium, a pair of sides will be parallel to each other.

Here, in the given figure JM is parallel to KL, thus forming a pair of parallel lines.
