Answer» Answer: Step-by-step explanation: ANSWER:- What is perimeter? The total SUM of the sides of a figure is called a perimeter. This contains BASIC arithmetic addition. In some solid shapes, we generally use direct formulas which were formulated earlier. According to question, 2a+b 4a+3b 7a-b are the sides given. Adding them all, we get $2a+3b+4a+3b+7a-b$ $\longrightarrow 13a-b \ is \ the \ answer.$ Some formulas for direct perimeter and area:- Perimeter of Rectangle = 2(L+B), where L and B are LENGTH and breadth. Area of rectangle is LengthBreadth. Perimeter of SQUARE is 4side. Area of square is $a^{2}$ where a is side. Perimeter or circumference of circle is 2pie*r Pie value is 22/7 or 3.14 Perimeter of triangle is side+side+side. While are is Heron's formula. $s = \frac{a+b+c}{2}$ where s is semi perimeter. $Area = \sqrt{s(s-a)(s-b)(s-c)}$ , for area of triangle. In case of right angle triangle:- $\frac{1}{2}\times base \times height$ .
