Answer:

Answer (1)

Given :-

• Perimeter of rhombus = 12.8 cm

To Find :-

Length of one side

Solution :-

As we know that

$\tt \: Perimeter \: of \: rhombus = 4 \times side$

$\tt \: 12.8 = 4s$

$\tt \: s \: = \dfrac{12.8}{4}$

$\tt \: s = 3.2$

Length of one side of rhombus is 3.2 cm

Answer (2)

Given :-

• Area of rectangle = 106.5 cm²
• Breadth of rectangle = 7.5 cm

To Find :-

Length of rectangle

Solution :-

As we know that

$\tt \: Area \: of \: rectangle = length \times breadth$

$\tt \: 106.5 = length \: \times 7.5$

$\tt \: length \: = \dfrac{106.5}{7.5}$

$\tt \: length \: = 14.2 \: cm$

Answer (3)

Given :-

• Base of triangle = 12 cm
• Altitude of triangle = 7.5 cm

To Find :-

Area

Solution :-

As we know that

$\tt \: Area \: of \: triangle = \dfrac{1}{2} \times base \times height$

$\tt \: Area \: of \: triangle = \dfrac{1}{2} \times 12 \times 7.5$

$\tt \: Area \: of \: triangle = 6 \times 7.5$

$\tt \: Area \: of \: triangle = 45 \: cm$

Answer (4)

Given :-

• Length of paper = 16 inches
• Area of paper = 48 inches²

To Find :-

Length of paper

Solution :-

As we know that

$\tt \: breadth = \dfrac{ Area}{Length}$

$\tt \: Breadth= \dfrac{48}{16}$

$\tt \: Breadth = 3 \: inches$

Answer (5)

Given :-

• Area of Parallelogram = 54 cm²
• Base of Parallelogram = 6 cm

To Find :-

Height of Parallelogram

Solution :-

As we know that

$\tt \: Height = \dfrac{ Area}{Base}$

$\tt \: Height = \dfrac{54}{6}$

$\tt \: Height = 9 \: cm$
