Question

the base of isosceles triangle is 16cm and it's area is 48sqcm. find perimeter

Answer 1

perimeter is 39cm.Area is given so find out the height.Then by using Pythagoras theorem find the hypotenuse and then add the sides which gives the perimeter.

Answer 2

$1 \div 2 \times 16 \times h = 48 \: therefore \: h = 6 \: so \: by \: pythagora \: you \: will \: have \: one \: side \: of \: isosceles \: triangle \: as \: 10 \: therefore \: perimeter \: is \: 10 + 10 + 16 = 36 \: is \: the \: correct \: answer \: may \: it \: help \: you$
