Answer:

d= 17.03

Step-by-step explanation:

$d=\sqrt{ (x_{2}-x_{1})+(y_{2}-y_{1})^{2}}\\\\d=\sqrt{(8--3)+(-6-7)^{2}}\\\\d=\sqrt{(11)+(-13)^{2}} \\\\d=\sqrt{121+169}\\\\d= \sqrt{290} \\\\d=17.03$

The area of a rectangle is 1,036 cm and its length is 74 cm.

Nikitich [7]

Answer:

(i) Breadth = 14 cm

(ii) Perimeter = 176 cm

Step-by-step explanation:

Given,

Area of a rectangle = $1036$ cm²

Length = $74$ cm

(i) Breadth = ?

We know that, Area of a rectangle = length × breadth.

Then,

$1036 = 74 \times Breadth\\1036 \div 74 = Breadth\\\boxed{\bf\:14 \:cm = Breadth }$

(ii) Perimeter of a rectangle = 2 (length + breadth)

Then,

$Perimeter = 2(74 + 14)\\Perimeter = 2(88)\\\boxed{\bf\: Perimeter = 176 \: cm}$

$\rule{150pt}{2pt}$
