Question

The base of a triangle is 14cm and height is 8cm the area of a rectangle is?

Answer 1

Answer:

$\setlength{\unitlength}{1.5cm}\begin{picture}(6,2)\put(7.7,2.9){\large{A}}\put(7.7,1){\large{B}}\put(10.6,1){\large{C}}\put(8,1){\line(1,0){2.5}}\put(8,1){\line(0,2){1.9}}\put(10.5,1){\line(-4,3){2.5}}\put(7.3,2){\mathsf{\large{8 cm}}}\put(9,0.7){\matsf{\large{14 cm}}}\put(8.2,1){\line(0,1){0.2}}\put(8,1.2){\line(3,0){0.2}}\end{picture}$

$\rule{160}{1}$

$\underline{\bigstar\:\textsf{Area of the Triangle :}}$

$:\implies\tt Area = \dfrac{1}{2} \times Base \times Height\\\\\\:\implies\tt Area = \dfrac{1}{2} \times14 \:cm \times 8 \:cm\\\\\\:\implies\tt Area = 7 \:cm \times 8 \:cm\\\\\\:\implies\underline{\boxed{\red{\tt Area = 56 \:cm^{2}}}}$

⠀

$\therefore\:\underline{\textsf{Area of the Triangle is \textbf{56 cm ^2 }}}.$

Answer 2

Answer :

$\large\sf\red{Area\:of\:Triangle\::{\frac {1}{2} \times base \times height}}$

$\large\longrightarrow\mathtt{\frac {1}{2} \times 14cm \times 8cm}$

$\large\longrightarrow\mathtt{56 cm^2}$

Step-by-step explanation:

★ What is a triangle?

→ We can say a triangle is a shape/polygon which is 3-sided.

★ Types of triangles?

→ Equilateral Triangle = whose all sides are equal.

→ Isosceles Triangle = whose two sides are equal.

→ Scalene Triangle = whose three sides are not equal.

★ Some other formulas :

• Area of parallelogram = Base × Height
• Area of trapezium = 1/2(a + b)h
• Area of rhombus = 1/2(product of it's diagonals)
• Area of rectangle = length × breadth
• Area of square = side × side = (side)²
